Abstract: Electro-mechanical switches and memory cells using vertically-disposed nanofabric articles and methods of making the same are described. An electro-mechanical device, includes a structure having a major horizontal surface and a channel formed therein. A conductive trace is in the channel; and a nanotube article vertically suspended in the channel, in spaced relation to a vertical wall of the channel. The article is electro-mechanically deflectable in a horizontal direction toward the conductive trace. Under certain embodiments, the vertically suspended extent of the nanotube article is defined by a thin film process. Under certain embodiments, the vertically suspended extent of the nanotube article is about 50 nanometers or less. Under certain embodiments, the nanotube article is clamped with a conducting material disposed in porous spaces between some nanotubes of the nanotube article.  Under certain embodiments, the nanotube article is formed from a porous nanofabric. Under certain embodiments, the nanotube article is electromechanically deflectable into contact with the conductive trace and the contact is either a volatile state or non-volatile state depending on the device construction. Under certain embodiments, the vertically oriented device is arranged into various forms of three-trace devices. Under certain embodiments, the channel may be used for multiple independent devices, or for devices that share a common electrode.
Patent CA-2517919-A1 (CA)
Title: Polished rod rotator
Inventor: ALI-ZADE VAGIF
IPC: E21B33/03
Filed: 2005-08-18
Abstract: Under low reservoir pressure in oil well bores, oil extraction is carried out by using pumping equipment, which activates submerged pump through up and down reciprocating sucker rods. Tubing rotators and rod rotators are utilized to increase the efficiency of this pumping equipment. The purpose of rod rotators is to prevent unwanted unscrewing of sucker rods, increase longevity of tubing and sucker rod strings that continually wear against each other, decrease deposits on the walls of tubing during the extraction of oil with high wax or paraffin content.
Patent CA-2519280-A1 (CA)
Title: Write-once-read-many storage system and method for implementing the same
Inventor: HELLER JEFFREY L
IPC: G06F17/30
Filed: 2004-03-05
Abstract: A write-once-read-many (WORM) storage system that employs large-capacity and relatively inexpensive disks in connection with a file system on a file server is pro-vided. The file system contains most or all of the required WORM  functionality so as to impose a minimal footprint on client applications, client operating systems and open protocols if desired. The system is organized around WORM storage volumes that contain files that, when committed to WORM storage, cannot be deleted or modified. Any file path or directory tree structure used to identify the file within the WORM vol-ume is locked and cannot be deleted. In one embodiment, the administrator creates a WORM volume, capable of storing designated WORM files. The client then creates an appropriate WORM file using the appropriate protocol semantics. The file is written to the volume and committed by transitioning the file attributes from a not-read-only to a read-only state. The file system recognizes the persistently stored WORM attribute of any file in a WORM volume as WORM file.  Henceforth, any attempt to modify the file attributes, write to the file, or delete the file, by clients, administrators or other en-tities is rejected and a request denied message is returned to the attempting party.

Abstract: A system and method is described herein for an exchange to act based on a market event on behalf of a trader. According to one aspect, a first electronic market can send orders to and/or manage orders at a second electronic market based on an internal and/or external market event on behalf of a trader. According to another aspect, an electronic market may manage orders in its own market based on an external market event on behalf of a trader. In particular, a trader, and exchange, or some other party can define an internal or external market event that comprises a condition and an action.  Upon receiving internal and/or external information, when the market event condition is satisfied, the electronic market performs the action associated with the condition. An advantage, among many others, of the present embodiments is that it makes internal and external market influences and conditions visible to electronic markets to facilitate trading on behalf of a trader.

Abstract: L'invention concerne un système et un procédé de reconnaissance, de classification et de localisation spatiale d'objets tridimensionnels finis. L'invention concerne notamment un procédé informatique de reconnaissance, de classification et localisation d'objets. Ce procédé consiste à générer une base de données d'entraînement sur la base d'un grand nombre de vues d'entraînement enregistrées par une caméra ou mises au point à l'aide d'une représentation d'un objet assistée par ordinateur. Des courbes caractéristiques sont dérivées des vues d'entraînement et des primitives des courbes sont détectées. Des descripteurs intrinsèques et extrinsèques de caractéristiques sont stockés dans une base de données conjointement avec des données relatives à la classe de l'objet et à la pose de la vue. Finalement, la reconnaissance se fait en deux étapes : premièrement, les descripteurs intrinsèques de la vue de reconnaissance sont comparées à ceux de la base de données ; deuxièmement, sont explorées, parmi les meilleures caractéristiques de rapprochement, celles qui s'accordent mutuellement dans le sens où elle suggèrent la classe même d'objet pour la même pose.

Title: Endovascular guide for use with a percutaneous device for harvesting tubular body members
Inventor: JOYCE STEPHEN J
IPC: A61B17/00
Filed: 2004-11-08
Abstract: A percutaneous harvesting device for the harvesting of tubular body members from a body is disclosed. The percutaneous harvesting device includes an endovascular guide for sufficiently straightening the tubular vessel to be removed and a perivascular cutting tool that is inserted over the endovascular guide. The cutting tool is advanced along the length of the tubular body member to be removed and it cuts body tissue (wherein the tubular body member is positioned inside the body tissue) as it is advanced. The body tissue is thus dissected from the body and can then be extracted percutaneously and rapidly from the body by pulling the endovascular guide, and the tubular body member and surrounding body tissue, from the body. The endovascular guide has one or more openings formed on the surface of the endovascular guide. The openings allow for introduced fluid to escape facilitating the removal of the endovascular guide from a tubular body member.
